I have the XSV boss pro bolt and it works great. Running at 140 psi with 3ms dwell and the short spring makes my Axe very quiet and smooth. Boss customer service I saw winter settings for the regular boss bolt posted on this forum so I asked what settings I should run with the pro and I got an answer within 2 minutes from Boss.

So I picked up an axe a little while back and I wanted to convert it to a axe pro and the Boss bolt was the first step for me. It was the best performance for price I have purchased. There are tons of videos out there that show you how begin using the kit and then tune the axe for great performance. After breaking in the bolt with 2 cases and tuning the axe, I now get 12 pods running my axe at 160 psi with the yellow spring and I get such a smooth shot. Great product with great support. I had to call boss twice and both time I was given great support and taken care of to satisfaction.
